I read with interest the article by Ed Peters headlined, 'One local price, baht another for foreigners' (South China Morning Post, February 13). Thailand is not the only place to discriminate on pricing, as we have found out on our travels.

My husband is Russian, and we encounter the same problem there in the museums and art galleries, as well as restaurants.

The Russian Museum in St Petersburg wanted to charge me about 10 times the amount my husband paid. After complaining to the curator, I decided to go back only when the prices are equal. In some museums, I have been able to 'appear' Russian by attentively listening to my husband talking to me as a way to get around this ridiculous problem.

In restaurants, there will often be two columns on the menu, with one price for locals and the more expensive column for foreigners. It will be interesting to see how they will charge our baby son when he grows up. He is, after all, half Russian.

Another country in which we have noticed unusual pricing is India, where if foreigners don't check the prices, they can end up paying too much. One vendor tried to charge us three times as much as the printed price for Coca-Cola, showing surprise when we pointed out the price discreetly marked on the top of the bottle.
